Operating system boot mode change (021) / unable to enter pass code

[Stephanie7]

I want to change the boot options so that I can get a dual boot windows 10 / linux.
For this, I shoukd disable the secure boot option. I found it easily but in order to save the changes, I should enter a 4 digit pass code and hit enter. If I don't want the change to be saved, I should just hit the escape key.
I am unable to enter the requested pass code. The system simply does not take it. I checked with assuming the keyboard would be set differently (azerty or qwertz) but the system just does not want to take any input except the escape key.
Any idea how to have it corrected.
For your info, in another forum, someone suggested to enable the legacy boot + disable the secure boot but it does not work for me either. I am still stuck on the message 021 with only the ESC key working.
Also, the laptop is brand new, the only thing I did so far was downloading Skype and Sugou (to be able to type chinese characters). I did not even set any user password.
Thanks in advance for the suggestion.

@Stephanie7,

Welcome to HP Forums, this is a great place to get support, find answers and tips,

Thank you for posting your query, I'll be more than glad to help you out 🙂

As I understand the computer is asking to "BIOS password" and you need assistance with the same,

You would have to contact HP phone support for a hardware service as the motherboard may require a tattoo/Bios Flash.
